commit: d9af6856bd7db9a88136723aeef8837dbbf4e1cf [5/32] ipc: add new SEM_SET command for sys_semctl() call
config: x86_64-randconfig-s351 (attached as .config)

All error/warnings:

ipc/sem.c: In function 'semctl_down':
ipc/sem.c:1093:25: warning: the omitted middle operand in ?: will always be 'true', suggest explicit middle operand [-Wparentheses]

vim +1093 ipc/sem.c
  1083		int err;
  1084		struct semid64_ds semid64;
  1085		struct kern_ipc_perm *ipcp;
  1086	
  1087		if (cmd == IPC_SET || cmd == SEM_SET) {
  1088			if (copy_semid_from_user(&semid64, arg.buf, version))
  1089				return -EFAULT;
  1090		}
  1091	
  1092		ipcp = ipcctl_pre_down(ns, &sem_ids(ns), semid,

  1095		if (IS_ERR(ipcp))
  1096			return PTR_ERR(ipcp);

  1098		sma = container_of(ipcp, struct sem_array, sem_perm);

  1100		err = security_sem_semctl(sma, cmd);
  1101		if (err)
  1102			goto out_unlock;
